Digital BW, The Print

Well darn, but no one tried it.  :(

I got one DTP70 user, a score of Eye1 users, and one DTP40 user. No
one with a Spyder. I am still willing to try it with a Spyder user (or
two!)   :)

1) Contact me for master curve for your printer and K7/K6 ink
combination. I will email it with installation instructions.

2) Create a target that will give you 256 patches of RGB gray from
(0,0,0  to  255,255,255) that Spyder can read. Do NOT scramble the
logical order from 0 - 255 unless you can unscramble when you export.

3) Print this target with the master curve I supply and the
Piezography workflow for QTR (not the QTR worfkow for QTR).

4) Measure the target

5) Export me a data file according to David's instructions.

contact me off list to send this to my email address...

Thanks in advance.

Jon
